<p>There is provided a method for processing a variable length code encoded image comprising a plurality of scan lines, wherein each scan line comprises a number of original code blocks comprising a differentially encoded parameter. The method comprises defining a subarea of the image comprising parts of a number of said scan lines, extracting the subarea, generating a set of auxiliary code blocks comprising an auxiliary differentially encoded parameter based on the first differentially encoded parameter of a first code block of a first current scan line in the subarea, and associating the auxiliary code blocks with the subarea. There is also provided an apparatus and a computer program product thereof.</p> |
